Large cracks in the ground along Avonside Drive.
The driveway of a house on Avonside Drive. One of the concrete slabs has broken apart from another and lifted to create a gap between them.
Cracking along the bottom of a house in Avonside Drive. The house has lifted a few centimetres off its foundations.

A merry-go-round at Sullivan Park in Avonside. Its base is covered in dried liquefaction.
A broken driveway on Avonside Drive. The concrete slabs on the driveway have lifted during the earthquake, creating a large crack in the driveway. The crack has been filled with tiles and wood but the rubbish bins have still fallen in.

A damaged property on Avonside Drive. Cracks can be seen running through the lawn. A woman is standing on a slab of concrete that has been raised by the earthquake.

A substantial crack in the lawn of a house on Avonside Drive.
The north end of the bridge on Gayhurst Road. During the earthquake, the bridge was forced about 15 centimetres towards the river, the land falling away under the road. Fencing has been placed around the footpath, and the road filled and resealed so that it can still be used by traffic.
Cracking along the pavement at Halswell Primary School. The ground has risen and fallen in places leaving an uneven surface where the children usually play.

Cracks along the road in Avonside Drive. The riverbank has slumped towards the river, separating the land from the road and creating these cracks. Road cones warn drivers of the uneven surface. In the distance, a pile of liquefaction can be seen in front of a house.

The driveway of a house on Avonside Drive. One of the concrete slabs has lifted and the owner has tried to fill the gap with blocks of wood. Unfortunately, these have come loose and are sticking out of the hole.

Detailed studies on the sediment budget may reveal valuable insights into the successive build-up of the Canterbury Plains and their modification by Holocene fluvialaction connected to major braided rivers. Additionally, they bear implications beyond these fluvial aspects. Palaeoseismological studies claim to have detected signals of major Alpine Fault earthquakes in coastal environments along the eastern seaboard of the South Island (McFadgen and Goff, 2005). This requires high connectivity between the lower reaches of major braided rivers and their mountain catchments to generate immediate significant sediment pulses. It would be contradictory to the above mentioned hypothesis though. Obtaining better control on sediment budgets of braided rivers like the Waimakariri River will finally add significant value to multiple scientific and applied topics like regional resource management. An essential first step of sediment budget studies Is to systematically map the geomorphology, conventionally in the field and/or using remote-sensing applications, to localise, genetically identify, and classify landforms or entire toposequences of the area being investigated. In formerly glaciated mountain environments it is also indispensable to obtain all available chronological information supporting subsequent investigations.
